Hello the list,

I thank you all for your answers, that bring me new questions

First, I managed to access my asteroid database which was copied on the
hard drive and I added the file soft02bright.txt in the guide directory.
I noticed that the magnitude is not displayed for the asteroid that I
copied on my hard drive ( from the guide CD)
but I could see the magnitude of the asteroids that come from the
soft02bright.txt file (asteroid that are in opposition in 2004).

Example :
for ceres mag 0.0 (asteroid database)
for pallas mag 9.3 (file soft02bright.txt), ceres is not in this file
because it is not at the opposition now.

Do you know what is wrong ?

Secondly, I wondered if it is possible to see graphically the asteroids
that come from the file inserted with ' Extra, Add asteroid from MPC '
and those that are in the asteroid directory or in the MPCorb.dat.

It would be useful for example if we want to gaze only the asteroids
that are in opposition ( = soft02bright.txt )

Finally, is it possible to remove the data which come from the file
inserted in ' Extra, Add asteroid from MPC '.
It seems to me that the only way to remove them is to enter the
comets.dat file and delete them.

Best regards
